While the supermarkets don't have cheap days, campaign director Joel Gibson said consumers would have less competition if they shopped early in the week or after hours. 'The prices don't change by day but there are fewer crowds on Mondays and Tuesdays, and you sometimes get end-of-day discounts on stock if you shop at night,' he told Daily Mail Australia. Mr Gibson, the author of Kill Bills, said supermarkets tried to clear out perishable items at night and launched new specials on Wednesdays, when they all distributed their new catalogues with the latest weekly deals. German cut-price supermarket chain Aldi has blueberries at $3.98 for a 250g punnet as well as Indian food-themed specials like a samosa maker for $40 Coles special deals include 575g boxes of Weet Bix for just $1.90 am for $3, and four Handee Ultra Paper Towel rolls for $2.75, as well as bacon for $3.50 per 250g While you might miss out on the new specials, you could pick up over stocked items for even less.
